Temperate evergreen forests, coniferous, broadleaf, and mixed, are found largely in the temperate mid-latitudes of North America, Siberia, Canada, Australia, Africa, Scandinavia, Indonesia, Malaysia, Amazon and Orinoco basins of South America, Himalayas and western ghats of India and Andaman and the Nicobar Islands.

These alveoli are the smallest types of lung tissue, and one of the most important. In addition to being the primary means by which oxygen enters and carbon dioxide escapes the bloodstream, these small pouches of air are also the reason why the lungs do not totally collapse when a person breathes out. This is because they contain a cell that secretes a special chemical to lower the surface temperature to prevent lung collapse. The alveoli also contain other cells that secrete chemicals to attack and remove any foreign objects in the lungs, such as dust, dirt and other debris.
In addition to making up alveolar sacs, alveoli also form alveolar ducts. It is estimated that there are more than 300 million alveoli in the human lungs, all of which are located in either alveolar ducts or sacs that are found at the end of the smaller passageways, or bronchioles, in the lungs.
SHORT ANSWER:
Alveolar sacs contain tiny pouches called alveoli, whose primary function is gas diffusion. These clusters of alveoli have thin walls that allow oxygen to pass easily from the lungs into the bloodstream and carbon dioxide to flow from the blood to the lungs so it can exit the body.
9:3:3:1 is the ratio.
From the given data,
We have a 9.8 two, ratio since we have 49/5, 15/5, 18/5, and 5/5.
This ratio resembles nine a little bit, which is what we inferred from the opposition's score.
When the two relevant genes exhibit independent assortment, this is the result. Therefore, the chromosomes/genes are not connected.
We are finally getting a ratio of 9:3:3:1
In flies, two possible outcomes for the body color phenotype is black and brown.
Whereas in eye color we have white eye and red eye.
Here, white eye is recessive and red eye is dominant
<h3>What does the independent assortment law entail? </h3>
- According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes.
- In other words, an allele for one gene does not affect the allele for another gene that a gamete acquires.
<h3>Where can I find independent assortment?</h3>
- Meiosis I of gamete production, when homologous pairs line up in random orientations at the center of the cell as they prepare to split, provides the physical foundation for the law of independent assortment.
